Abstract
The utility model discloses a flame-retardant shielding cable for a computer, which comprises three conductor units. The three conductor units are arranged in upside-down T-shaped manner, each conductor unit consists of two conductors which are mutually stranded, insulation layers are wrapped outside the two conductors, an inner lapped layer and a branch shielding layer are sequentially wrapped outside each conductor unit, an outer lapped layer and a general shielding layer are sequentially wrapped outside the conductor unit wrapped by the branch shielding layer, drain wires are arranged among the inner lapped layer, the branch shielding layer, the outer lapped layer and the general shielding layer, three columnar packing ropes are arranged between the outer lapped layer and the branch shielding layer, an inner protective layer, an armored layer and a sheath layer are sequentially wrapped outside the general shielding layer, and allowable bending radius of the cable is not less than twelve times of the outer diameter thereof. The structure of the cable is more compact due to the fact that the three packing ropes are arranged between the outer lapped layer and the branch shielding layer. Meanwhile, shielding effect of the cable is effectively improved due to the drain wires intermittently contacting with the shielding layers, and accordingly safety performance is greatly improved.
Description
Technical field:
The utility model relates to computer cable, relates in particular to a kind of computer shielded type cable with flame-retarding characteristic.
Background technology:
Cable is in order to transmit electricity (magnetic) energy, the wire product of information and the conversion of realization electromagnetic energy.Normally by the cable of several or at least two every group stranded similar ropes that form of several groups of leads, mutually insulated between every group of lead, and often be twisted into round a center, whole outside is surrounded by the cover layer of high-insulation.
Electric wire mainly comprises bare wire, electromagnetic wire and electrical equipment and electrical insulated electric conductor, power cable, telecommunication cable and optical cable.
The computer cable of previous flame-retarding characteristic, structure is compact inadequately, intensity is lower, shield effectiveness is bad, and the utility model is to be applicable to that industries such as ac rated voltage 300/500V electric power, metallurgy, petrochemical industry make control line and detecting instrument instrument computer cable based on automatic control system, computer distributed control system, the automation control system of electronic computer.Be provided with three column gasket for packings outside between lapping layer and the sub-shield, make that the structure of cable is compact more, be provided with simultaneously with screen and be interrupted the drain wire that contacts, improved the shield effectiveness of cable effectively, security performance promotes significantly.
The utility model content:
The purpose of this utility model provides a kind of computer shielded type cable with flame-retarding characteristic, be applicable to that automatic control system, computer distributed control system, automation control system based on electronic computer make control line and detecting instrument instrument computer cable, compact more before structure was compared, intensity improves, shielding properties promotes.
The technical solution of the utility model is as follows:
Computer shielded type cable with flame-retarding characteristic, comprise three conductor groups of arranging in a triangle, described conductor group is enclosed with by two outsides respectively that the conductor of insulating barrier is mutually stranded to be constituted, it is characterized in that: the described conductor group outside is enclosed with interior lapping layer respectively successively, sub-shield, the conductor group of parcel sub-shield is enclosed with outer lapping layer outward successively, total screen, lapping layer and sub-shield in described, be provided with drain wire between outer lapping layer and the described total screen, described drain wire and sub-shield, the contact that total screen is interrupted, be provided with three column gasket for packings between described outer lapping layer and the described sub-shield, described total screen outside is enclosed with sheath successively, armour, restrictive coating, cable permission bending radius is not less than 12 times of external diameter.
Described computer shielded type cable with flame-retarding characteristic is characterized in that: described sub-shield, total screen all adopt the wrapped formation of copper strips.
Described computer shielded type cable with flame-retarding characteristic is characterized in that: described restrictive coating material adopts flame-proof polyvinyl chloride.
The utility model has the advantages that:
The utility model is provided with three column gasket for packings between lapping layer and the sub-shield outside, make that the structure of cable is compact more, be provided with simultaneously with screen and be interrupted the drain wire that contacts, effectively raise the shield effectiveness of cable, security performance promotes significantly, has high-low temperature resistant, corrosion-resistant and to the advantage of grease proofing soda acid in addition.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
